Charge the phone until the led light turns green. Then unplug, turn the power OFF (Don't just put it to sleep, power the phone off completely) then plug it in (the led light should now be red) charge until the light turns green again, probably like 10 or 20 minutes. Makes a big difference! I learned this in another thread but I can't find it now. Thanks to the original poster! Update 1: I did this method again this morning 10am. It's now almost 11pm and I still have a 60% charge! I made several short phone calls, checked email, texts throughout the day, and took about 35 pics. I also spent a fair amount of time looking at them. Granted I wasn't on the phone as much as the first few obsessive days of owning this baby but still, I'm very happy with this battery trick. Update 2: I want to add this quote by 'jasonb1985' from a different thread: "if you take it off of the charger right as the light turns from orange to green then you'll actually have a full charge. if you let it charge overnight then you'll wake to a phone that quickly falls into the mid 90's." I have to agree with this. Even with my charging method above, if you let it stay on the charger too long after it turns green for the second time, the battery level will quickly drop after removing it from the charger. I've found it's better to remove it around the 20/30 minute mark even if the light is still red rather than let it sit there and miss when it turns green. Of course the best case scenario is to take it off the charger the moment it turns green but that's not very practical. One more thing I've noticed is that if you spend a lot of time in a location where there is little or no reception such as a hotel or basement etc, your battery will drop very fast. Best to put it in airplane mode in those situations if possible.
